void ADLER32_CalculateHex( [ out ]ADLER32_HexDigest* pDest, [ in, size_is( nSrcLength ) ] const void* pSrc, [ in ]int nSrcLength, [ in ] boolean bUpper );



    [out] A memory buffer that will receive the checksum as an ASCII null-terminated string.

     Note. All predefined types are specified in the Predefined Types List.


    [in] A continuous memory block for which to calculate the checksum.


    [in] Length in bytes of the memory block.


    [in] Uppercase flag. If bUpper is False, the received checksum represents a lowercase string, otherwise it represents an uppercase string.


Calculates the ADLER32 checksum for the pSrc memory block. The checksum is retrieved as an ASCII null-terminated hexadecimal string in the pDest memory buffer. 

VB Example

Private Sub MyButton_Click()   
    Dim Checksum As ADLER32_HexDigest
    Dim MyStrData As String
    MyStrData = "Hello World!"
    Dim nLen As Long
    nLen = Len(MyStrData)
    'Convert the string to byte array
    Dim MyBinData() As Byte
    ReDim MyBinData(1 To nLen)    
    For i = 1 To nLen
        MyBinData(i) = Asc(Mid(MyStrData, i, 1))
    Next i    
    'Get the checksum
    ADLER32_CalculateHex Checksum, MyBinData(1), nLen,  True
    'Show the hexadecimal representation of the checksum 
    MsgBox QHASH_ASCIItoBSTR(Checksum.Value(0))
End Sub
